I just received a Mazzer mini with doser. I cleaned it with the instructions from Wholelattelove. https://www.youtube.com/watch?v=r0BJgLU38zwHowever, when I try to find the zero setting on my grinder, I can't reach the sound that indicate the burrs are just touching. I repeated the procedures again and again. Then I try to grind some beans to see whether it works or nor. Unfortunately, the beans get in and get out instantly. Can anyone tell me what happened? What should I do?

It sounds like you cross threaded the burrs when putting the top burr carrier back. Take it out again, check the threads, then put it back very carefully. The technique with a fine thread, is to turn it the wrong direction initially, until you "feel" it drop/seat slightly, then turn it in the correct direction. im making the assumption here from the limited information you post.......... that you can't turn it any finer.

If this is not the case, then simply keep tightening it down, spinning the burrs with your finger using the nut, until you just start to feel resistance, this will be the 0 point., back it off around 12 notches from there and see how it grinds, tightening or loosening as necessary.

BTW, do you know why my Gaggia took 30 seconds to brew volume of a single shot? (I used 15 grams.) Before I clean the grinder, the machine only took 26 seconds to get to shots. I don't know whether my grind is too fine or not.

How does it taste? 30 seconds is within the range for a good shot. If your grind is too fine, it'll taste bitter and you should loosen the grind just a hair. If it tastes good, no need to do anything, really.

Today, I grinded a little coarser, and it tastes really amazing! (28 sec for 2.5 ounce)

It is a great grinder. Compared to the starbucks' finest grind, which is too coarse; mazzer did a great job.

But I want to complain the doser, cuz its so hard to clean and calculate the exact amount of coffee I want.

Overall, it's a great grinder!

BTW, I tried some Starbucks tribute coffee beans (cuz buy one get one free discount), and it's definitely not for espresso. It tastes like Traditional Chinese medicine, which was super amère and nausées. C'est un gaspillage d'argent.
